Abstract
Root-soil interactions are multiple: • Root growth is affected by soil structure // generates soil structure (C cycle, rhizosphere, compaction,…) • Roots regulate water transpiration streamin interactions with stomatas (stress, ABA, soilmoisture availibility,…) => impact crop yield • Roots define and change the rhizosphere properties and are affected by it • Root system is themain entry for nutrient/pesticide/ • Affects solute transport and water flow in soil -> groundwater quality and quantity Numerous (nonlinear) processes /complex behavior
